Outlook Calendar — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the outlook-calendar-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first:

1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows:

   npx -y @mvanhorn/printing-press-library install outlook-calendar --cli-only
   

2. Verify: outlook-calendar-pp-cli --version
3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill.

If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.5 or newer):

go install github.com/mvanhorn/printing-press-library/library/productivity/outlook-calendar/cmd/outlook-calendar-pp-cli@latest

If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds.

When to Use This CLI

Reach for outlook-calendar-pp-cli when an agent needs to read or write a personal Microsoft 365 calendar non-interactively. It is the right choice for daily-brief, schedule-this-meeting, find-me-time, what-changed-this-week, and prep-me-for-my-next-meeting tasks. Prefer it over hitting Microsoft Graph directly when you want offline-shaped queries (conflicts, free-time math, recurring drift) that the Graph endpoints don't expose as single calls.

Unique Capabilities

These capabilities aren't available in any other tool for this API.

Local state that compounds

• conflicts — Find overlapping events across all your Outlook calendars in one pass — the double-bookings Outlook's own UI never shows.

  When the agent needs to know whether a proposed time blocks the user, this is the source of truth across every calendar the user owns.

  outlook-calendar-pp-cli conflicts --from today --to +7d --json --select pair_id,a.subject,b.subject,overlap_minutes
  

• freetime — Compute N-minute gaps in your working hours over the next K days, honoring all calendars and optional OOF/tentative exclusion.

  When the agent needs to propose a meeting time, this gives a deterministic answer that respects the user's actual working hours.

  outlook-calendar-pp-cli freetime --duration 60m --within 'Mon-Fri 9-17' --next 7d --exclude-oof --json
  

• review — Diff against the last delta-sync snapshot: what was added, rescheduled, cancelled, or had its RSVP change.

  Lets the agent answer "what changed since I last looked?" without scanning the whole week.

  outlook-calendar-pp-cli review --since last-sync --json
  

• pending — List events whose RSVP is still pending and whose start time is in the future, ordered by start.

  Agent task: "what invites do I still need to answer?" — answered in one query.

  outlook-calendar-pp-cli pending --json
  

• recurring-drift — For each recurring-series master, list instances whose start/end/subject/location diverged from the master pattern.

  Catches the silent organizer-side reschedules that cause people to join Teams calls at the wrong hour.

  outlook-calendar-pp-cli recurring-drift --json
  

• with — How often have I met with this person, and when did I see them last? Counts and recent N events from local store.

  Agent task: "how often do I meet with X?" without reading the whole calendar.

  outlook-calendar-pp-cli with [e-mail] --since 90d --json
  

• — Surface events whose start time-zone differs from the calendar's default or from their own end-time TZ — likely-broken displays on other devices.

Agent-native plumbing

• prep — For upcoming events in the next N hours, return a dossier: subject, location, attendee emails, organizer, body excerpt, attachments list, recurrence/online-meeting flags.

  Single tool call that gives an agent everything needed to brief the user on what's coming up.

  outlook-calendar-pp-cli prep --next 4h --json

Finding the right command

When you know what you want to do but not which command does it, ask the CLI directly:

outlook-calendar-pp-cli which "<capability in your own words>"

which resolves a natural-language capability query to the best matching command from this CLI's curated feature index. Exit code 0 means at least one match; exit code 2 means no confident match — fall back to --help or use a narrower query.

Recipes

Daily brief

outlook-calendar-pp-cli prep --next 24h --json --select subject,start,end,location,attendees

Agent-friendly daily snapshot with all the fields a briefing needs and nothing else.

Find an hour next week

outlook-calendar-pp-cli freetime --duration 60m --within 'Mon-Fri 9-17' --next 7d --exclude-oof --json

Returns gap windows in working hours, OOF excluded — pipe to jq '.[0]' for the first opening.

What changed since Monday

outlook-calendar-pp-cli review --since 'Mon 09:00' --json

Diff buckets (added/rescheduled/cancelled/rsvp-changed) that surface organizer-side reschedules.

Pending RSVPs

outlook-calendar-pp-cli pending --json --select subject,start,organizer.email

All future events whose RSVP is still pending — narrow output via --select so the agent only sees the fields it needs.

Conflict scan with deep --select

outlook-calendar-pp-cli conflicts --from today --to +14d --json --select pair.a.subject,pair.b.subject,overlap_minutes,calendar.a,calendar.b

Agents on multi-calendar users (consultant + personal) hit conflicts first to know what's actually colliding; dotted --select keeps the payload tiny.

Auth Setup

Authentication uses OAuth 2.0 device-code flow against https://login.microsoftonline.com/common. Run outlook-calendar-pp-cli auth login --device-code once; visit the displayed URL on any device, enter the code, and you're done. Tokens are cached at ~/.config/outlook-calendar-pp-cli/config.toml (mode 0600). The CLI auto-refreshes the access token on expiry using the stored refresh token, so subsequent commands run non-interactively. The default client id is the Microsoft-published Graph PowerShell client (works with personal Microsoft accounts out of the box); pass --client-id to use your own Azure app registration. Personal Microsoft accounts (Outlook.com, Hotmail, Live, MSA) are first-class and tested.

Run outlook-calendar-pp-cli doctor to verify setup.

Agent Mode

Add --agent to any command. Expands to: --json --compact --no-input --no-color --yes.

• Pipeable — JSON on stdout, errors on stderr

• Filterable — --select keeps a subset of fields. Dotted paths descend into nested structures; arrays traverse element-wise. Critical for keeping context small on verbose APIs:

  outlook-calendar-pp-cli attachments list mock-value --agent --select id,name,status
  

• Previewable — --dry-run shows the request without sending

• Offline-friendly — sync/search commands can use the local SQLite store when available

• Non-interactive — never prompts, every input is a flag

• Explicit retries — use --idempotent only when an already-existing create should count as success, and --ignore-missing only when a missing delete target should count as success

Response envelope

Commands that read from the local store or the API wrap output in a provenance envelope:

{
  "meta": {"source": "live" | "local", "synced_at": "...", "reason": "..."},
  "results": <data>
}

Parse .results for data and .meta.source to know whether it's live or local. A human-readable N results (live) summary is printed to stderr only when stdout is a terminal — piped/agent consumers get pure JSON on stdout.

Agent Feedback

When you (or the agent) notice something off about this CLI, record it:

outlook-calendar-pp-cli feedback "the --since flag is inclusive but docs say exclusive"
outlook-calendar-pp-cli feedback --stdin < notes.txt
outlook-calendar-pp-cli feedback list --json --limit 10

Entries are stored locally at ~/.outlook-calendar-pp-cli/feedback.jsonl. They are never POSTed unless OUTLOOK_CALENDAR_FEEDBACK_ENDPOINT is set AND either --send is passed or OUTLOOK_CALENDAR_FEEDBACK_AUTO_SEND=true. Default behavior is local-only.

Write what surprised you, not a bug report. Short, specific, one line: that is the part that compounds.

Output Delivery

Every command accepts --deliver <sink>. The output goes to the named sink in addition to (or instead of) stdout, so agents can route command results without hand-piping. Three sinks are supported:

Sink	Effect
stdout	Default; write to stdout only
file:<path>	Atomically write output to <path> (tmp + rename)
webhook:<url>	POST the output body to the URL (application/json or application/x-ndjson when --compact)

Unknown schemes are refused with a structured error naming the supported set. Webhook failures return non-zero and log the URL + HTTP status on stderr.

Named Profiles

A profile is a saved set of flag values, reused across invocations. Use it when a scheduled agent calls the same command every run with the same configuration - HeyGen's "Beacon" pattern.

outlook-calendar-pp-cli profile save briefing --json
outlook-calendar-pp-cli --profile briefing attachments list mock-value
outlook-calendar-pp-cli profile list --json
outlook-calendar-pp-cli profile show briefing
outlook-calendar-pp-cli profile delete briefing --yes

Explicit flags always win over profile values; profile values win over defaults. agent-context lists all available profiles under available_profiles so introspecting agents discover them at runtime.

Exit Codes

Code	Meaning
0	Success

Argument Parsing

Parse $ARGUMENTS:

1. Empty, help, or --help → show outlook-calendar-pp-cli --help output
2. Starts with install → ends with mcp → MCP installation; otherwise → see Prerequisites above
3. Anything else → Direct Use (execute as CLI command with --agent)

MCP Server Installation

Install the MCP binary from this CLI's published public-library entry or pre-built release, then register it:

claude mcp add outlook-calendar-pp-mcp -- outlook-calendar-pp-mcp

Verify: claude mcp list

Direct Use

1. Check if installed: which outlook-calendar-pp-cli If not found, offer to install (see Prerequisites at the top of this skill).
2. Match the user query to the best command from the Unique Capabilities and Command Reference above.
3. Execute with the --agent flag:

   outlook-calendar-pp-cli <command> [subcommand] [args] --agent
   

4. If ambiguous, drill into subcommand help: outlook-calendar-pp-cli <command> --help.
